Novel Nanocomposite Materials for Efficient Photocatalytic

Novel Nanocomposite Materials for Efficient Photocatalytic Reduction of CO2 to Fuels Ying Li, Mechanical Engineering Department, University of Wisconsin-Milwaukee

We aim to develop novel nanocomposite materials to convert CO2 and H2O to fuels (e.g., CO and CH4) under UV-visible illumination  Cu, Ag, or Ce modified TiO2 nanoparticles as the photocatalysts  Ordered mesoporous SBA-15 as the catalyst support  In-situ DRIFTS analyses to understand the reaction mechanism
